Provided are a water- and oil-repellent agent and a copolymer that are superior in terms of water repellency, oil repellency and wear resistance. The present invention pertains to a copolymer formed by polymerizing constituent monomers containing at least a (meth)acrylate compound (a1) having a C1-6 fluoroalkyl group, an alkoxysilyl group-containing (meth)acrylate (a2) and a (meth)acrylate compound (a3) having a hydrocarbon ring structure.
